Abstract
A chip damage detection device is provided that includes at least one bi-stable circuit having a first conductive line passing through an observed area of a semiconductor integrated circuit chip for damage monitoring of the observed area. The at least one bi-stable circuit is arranged to flip from a first stable state into a second stable state when a potential difference between a first end and a second end of the first conductive line changes or when a leakage current overdrives a state keeping current at the first conductive line. Further, a semiconductor integrated circuit device that includes the chip damage detection device and a safety critical system that includes the semiconductor integrated circuit device or the chip damage detection circuit is provided.
